module translated_cylinder ( size_vector, idx = 0 ) Strings Integer from Numeric String (Decimal or Hex)Ĭonverts number in string format to an integer, (s2d - String 2 Decimal - named before I added hex to it.)Į.g. sizes =, ,, , ] // One option to solve this is by using a recursive module // that will create a new translated coordinate system before // going into the next level. All cylinders are to be stacked above each other (with // an additional spacing of 1 unit).
Define the sizes for the cylinders, first value is the // radius, the second is the height.

Create a simple recursive function that adds the values of a list of floats // the simple tail recursive structure makes it possible to // internally handle the calculation as loop, preventing a // stack overflow.
